Knee-Focused & Liner-Free Warmth

Built for lightweight warmth and cold-weather layering, the Women's Heated Baselayer Bottoms are a heated baselayer for the lower body, made for skiing, hiking, outdoor work, brisk walks or jogs, and everyday cold-weather wear — worn under pants or outer layers, or on their own as standalone leggings. This bottom uses a liner-free construction to reduce bulk and create a softer, more flexible next-to-skin feel. A 3-zone heating system covers the knees and core, while the streamlined fit makes them easy to layer under pants without getting in the way of movement. Worn with the Qtr Zip Heated Baselayer Top, they complete a heated base layer set that helps create warmth where you need it most.
